When to escalate a child's delay in understanding
A frontline health worker should escalate when a child understands clearly less than peers and the gap persists — for example no response to name or simple words by 18 months, or not following one-step instructions by 2 years in the home language. Any loss of understanding once present needs prompt referral, and hearing should always be checked first. This is a reason to assess early, never a diagnosis.
A frontline worker who pauses to notice how a child understands everyday words is already doing the most valuable early work there is.
In short
Escalate to a developmental check when a child clearly understands less than other children of the same age and the gap is persistent, not just shy-day behaviour — for example, by around 18 months not turning to their name or following simple words like come or give, or by 2 years not following easy one-step instructions in their home language. One firm rule: any loss of understanding a child once had needs prompt referral. This is a reason to assess early, never a diagnosis.What to watch (ICF d1, understanding)
Understanding — receiving and making sense of spoken words, gestures and routines — usually comes before talking. Refer for a developmental check when you see:- By 9–12 months — no response to their name, no looking when you point or wave bye-bye.
- By 18 months — not following simple familiar words (give, come, no) or pointing to a named object or body part.
- By 24 months — not following a simple one-step instruction without gestures, in the family's everyday language.
- At any age — losing words or comprehension once present, no response to sound, or a parent who feels their child "doesn't seem to hear or understand".
Always check hearing first — undetected hearing loss is the commonest, most treatable reason a child seems not to understand. Ask in the home language, not only in a clinic tongue.
When to escalate
Don't wait-and-watch a clear, persistent gap. Refer to a paediatrician or developmental service when a milestone window has passed, when there is any regression, or when a parent is worried — parental concern alone is a valid trigger.The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from a checklist in the field. Our team assesses how a child understands language and routines, and our speech therapy clinicians build comprehension through play.Trusted sources

Book a developmental assessment so a clinician can review the child's hearing, understanding and milestones early.

What to watch
Refer if a child doesn't respond to their name by 9–12 months, doesn't follow simple familiar words or point to named objects by 18 months, or can't follow a one-step instruction in the home language by 24 months. Always check hearing first. Any loss of understanding once present, or strong parental concern, warrants prompt referral.
Try this at home
Test understanding in the child's home language with everyday words — ask them to fetch a familiar object or point to a body part, without using gestures or pointing yourself, and note how they respond.

Frequently asked
Should I refer based only on a parent's worry?
Yes — parental concern is a recognised, valid trigger for a developmental check. Parents observe their child every day, and their worry is useful clinical information. Refer for review rather than telling them to wait.
Why check hearing first?
Undetected hearing loss is the commonest and most treatable reason a child appears not to understand. A hearing check should accompany or precede any developmental referral for understanding delay.
Is wait-and-watch ever right for understanding delay?
Not for a clear, persistent gap or any regression. A single quiet or shy day is fine, but a milestone window that has passed, or loss of a skill once present, means refer now — early support works best.
